Daylight Saving Time may have sapped the ratings strength of mere mortal television shows over the past week, but it had little effect on Fox phenomenon “Empire,” which on Wednesday grew its audience for a ninth consecutive airing heading into next week’s two-hour finale.

According to preliminary national estimates from Nielsen, “Empire” averaged a 5.6 rating/17 share in adults 18-49 (down a tick from last week’s prelim score) to more than double the rating of any other program on the night.

In total viewers, it gained about 400,000 to set yet another milestone with 14.7 million. Last night’s episode of “Empire” also drew a series-high 750,258 tweets during the live broadcast, according to Nielsen Social Guide/Twitter. As a result, its average for the season (451,270) is now ahead of AMC’s “The Walking Dead” (444,029) and ABC’s “Scandal” (354,085).

“Empire” again more than doubled its “American Idol” lead-in (2.3/8 in 18-49, 9.3 million viewers overall) though the music reality competition was up a couple of ticks from last week to edge out CBS’ “Survivor” (2.2/8 in 18-49, 9.4 million viewers overall) both head-to-head and as the night’s No. 2 program in 18-49.
